Gapplet
Given a sequence g1, ..., gt of permutations, determine the centre of the group G generated by them.
Give a sequence of permutations, e.g., [2,3,1,6,4,5], [2,1,4,3,6,5], |
|
A set of generators of the centre of G written both as products of the generators
g1, ..., gt of G
and as permutations | |
